Cookie files gibberish & index.dat won't delete

My cookies were always listed as cookie:owner@xxxx.com but suddenly this week they were all converted to gibberish letters/numbers with the .txt file extension. I can click on these and when inside there is a lot more gibberish with a small section that actually shows who it is from. For example after clicking on your site a cookie appeared (2QLJX7VO.txt) and opening this up a section shows forum.piriform.com but I don't want to have to click on each cookie to identify it. So when I go to the temporary internet files folder it will show cookie:owner@forum.piriform.com as a text document and any time I delete those the related cookie is also deleted. I realize I can just delete all the cookies and start over but I was wondering how this happened? Running my anti-virus shows that everything is okay.

Also, previously, I had been able to delete the index.dat file with the CCleaner program but for some reason that is not working now.When I click on the analyze button for index.dat it shows 0 bytes even tho the file shows 144KB. Can someone tell me what is going on???

I am running Windows XP and have never had this happen before nor have I ever heard of it. Using CCleaner version 3.09.1493

Apparently a windows update has changed the way ie 8 handles and stores cookies.

It's mentioned by Bill P HERE and by EricLaw HERE about half way down.

I can't find specifically that ie 8 is affected, but a microsoft bulletin HERE implies that it is (3rd paragraph).

I run ie 8 wxp home, but haven't installed the updates yet, maybe some other member has and could confirm it.

Also mentioned on forum here, with a comment from a dev.

The latest (3.10) ccleaner handles the new ways of internet explorer cookies

(2500)

I now have the latest (3.10) CCleaner version but am still unable to delete any index.dat files.

In fact, the program just does not find those files. For example, when I click on the analyze button for index.dat it shows 0 bytes. But using windows explorer, the cookie folder has an index.dat file with 144KB not to mention all the other index.dat files in other folders. Previously, I could remove these files even tho it took a restart to accomplish the task.

Why is this not working now? And what can I do to clean up these type files???

This has nothing to do with this topic. I will give you the short answer, if you require a longer one you will need to start your OWN topic. it seems you are the original poster so this is slightly more understandable that you would post here.

Index.dat files are no longer removed, They are vacuumed empty (the internal data is removed). This has been true for a number of versions, and it is the suggested way of handling .dat files. There is no bug.

Yes, you are correct and I misstated saying that the file itself was removed.

But previously, it would clean (vacuum out) the file and now it doesn't do that. I think that the smallest I ever noticed that file's size it was 16KB, and I could see it gradually rise over time. I hadn't run the CCleaner for some time and decided it was time especially after seeing all the cookie names replaced with gibberish and the index.dat file increased to 144KB. I thought the two issues might be related. I don't really understand all the tech stuff for MS changing the cookie format but I guess it has something to do with better security.

However after analazing with CCleaner, it just says that there are 0 bytes. So the index.dat files are not being cleaned or even a portion of it.

Excuse me if I've used the wrong terminology in any of this. It still seems to me that this particular portion of CCleaner is not working correctly. Or maybe I'm doing something wrong. If anyone is able to remove the internal data from these files - what are the sizes before and after the cleaning?

Pointstone makes a free index.dat reader.

Have u verified this with an index reader program?
